Fridge and batteries

[catch-22]

gurday,

Am borrowing a Waeco CF110. It will be in my Disco II Td5 with a brand new NRMA battery to standard spec.

Will my normal car battery be OK to power the fridge overnight. Should I start the car every day??

Cheers
Caine

waeco's have a low voltage cutout from memory, i don't own one but you might want to check what thy are set at

i have engels and they do not have low voltage cutout standard so they caN/will leave you stranded......in saying that captain rightfoot ran his 40L engel on his first desert trip using only one battery, he was travelling with other cars but never needed a jump start

Looking at the specs, the current draw is

2.1 amps/hr average

So a 10 hour overnight will draw 21 amps (in theory) and you have a ??? amp/hr battery - if it is a good 85 - 100 amp/hr battery yes you should be good overnight.

Yes you would need a short run during the day to top your battery up - but not for long - maybe 20 mins.

The older Waecos ( like mine ) have three positions for the low voltage cut out ( hi, med and lo ). Before you go away, I'd suggest you do a test. Set everything up in the car, set fridge to the "med" position and run the fridge till it cuts out. If you still have enough juice to turn the starter motor, well and good. If not, you will need to set it to the "high" position.
( I'd be trying this while you still have someone nearby who can give you a jump start if needed. )

I don't think the newer Waecos have this selector switch so maybe it's not selectable, or adjustable in software ??

I wouldn't do it, but, if the new battery is the same spec as the original Delfi Calcium battery with 900CCA 110AH and you have the fridges battery cut out set too high which will stop it drawing power at 12volts then yes it should be OK.

The Waeco 110lte draws a lot of power, far more than the 40l or 50l jobbies, even though Waeco shows they don't, in the factory they might be good, but out in the bush the elements change things alot.

Remember the Disco TD5 needs a higher CCA and Amp Hour battery too the Defender and some battery places and organisations don't know this.

Get one of those Supercheap jump packs and run it off that overnight

You should be ok runing the fridge over night with a short run the next day but for peace of mind id get a jump start pack just incase or run the fridge solely from it i have one of theses in the link and it will run my fridge for up to 2 days depending on conditions and settings on the fridge

Tho you should be able to get this same item for 100 bucks or cheaper from any battery world or auto pro i payed 99 bucks for mine 5 years ago and its been a verry handy unit and still is :D:D:D

I have a charger and as I will be on a powered site, was going to run the charger overnight while the fridge is running.......

Considering the amount of imobiliser issues myself and others are "again" having on our D2's at the moment, I'd be cautious of putting any major drain on the battery overnight. It can lead to a world of hurt.

Also, make sure your power socket in the cargo area is in good condition and/or replace it with a more suitable unit (one that doesn't fall out on route) to power your fridge.

In that case why don't you just take a 240V extension lead and plug the fridge straight in to ther mains ?

The unit I am borrowing does not have that feature....it is on older one..

Oh I see ... well in that case the charger method will work ...as long as the ingoing amps is more than the outgoing amps.

Maybe the person you're borrowing the fridge from has the 240V external power pack for it ?

This would be the best option.

I agree, it would be....but either it is an older model and it is not an option or he just doesn't have the module....not sure which.

[waynep]

All the older Waecos had an optional external 240V power pack. Most people would have bought one so they could run the fridge indoors.
Later models had integrated 240V inside the firdge.

In fact you don't need to use a Waeco Power Pack. Any REGULATED/FILTERED 240V-12VDC power supply that supplies enough amps would do. ( I think the genuine Waeco ones are specified at 5 or 10 amps ). A standard battery charger is not normally regulated or filtered to the required extent, so needs to be connected to the battery which essentially does that job.

So looks like you'll go with the battery charger idea. That'll be fine, it is just a bit of a pain opening the bonnet and connecting the leads every night.

be careful with the low voltage cutout thing...

remember the electronic modules in the td5 powered rovers have a low voltage cut out as well, this is about 10.5v if you have less volts than that at the ECU when its trying to start it wont fire the injectors. If your alarm system see less than that it can also lock out the ECU so it wont start.

If the injectors dont fire.............

IF it were me ID be setting the fridges cut out voltage quite high on a single battery system say 11.5ish volts and if your battery is a couple of years old even higher (11.8-12v.)
